To all whom it may concern .t

Be it known that lf, THOMAS J. BUCKLEY, a citizen of the United States,and a resident of New Brunswick, in the county of Middlesex and State ofNew Jersey, have I invented certain new and useful Improvements inMachines for Printing Tubes, of which the following is a specication.

The invention relates to machines for printing metal containers andother articles in cylindrical or tubular form, and its objects, amongothers, are toproduce a device of this character of simple, durable andeffective construction and operation to provide for a higher eciency anda better `quality of work, and to provide for various adjustments of theparts to that end.

. The improvements reside in the construc. tion and arrangement of partshereinafter described and claimed and illustrated in the accompanyingdrawings.

In the said drawings, Figure 1 is a side elevation of a machineembodying the improvements. Fig. 2 is an enlarged elevation of certainparts of the machine viewed from the opposite side to Fig. 1. Fig. 3 isa plan of some of the parts shown in Figs. 1 and 2.

The framework ofthe machine consists of twoparallel u right frames 41and 2 spa-ced apart and having recesses 3 and t therein, in which areadjustably mounted sliding journal blocks 11 and 1 2'provided withadjusting screws 13 and 14,' and springs also mounted in the frames, formoving the same. ln these journal blocks vrotate the ends of the shaftson vwhicliy the 'bed-plate roller 20 and inking roller 21 (see dottedlines Fig. 1) are mounted. The ehafts on which other rotary, members otthe machine are mounted also have theirv journals in the said frames,lthe journal at one end being mounted in the frame on one l side and thejournal at the other end being mounted in the opposite frame. 'llhisincludes the pulley shaft 22, the cam Shaft 2B, the segment gear shaft24: and the idler shaft 25.

lnk is supplied to suitable rollers 26,21 and 28 mounted in verticalslots in the supplemental upright frames 5, and the lowermost of theserollers, 28,.are in Contact with the large inking rolleror cylinder 21,which te Speciucation of Letterslatent.

reief figures adapted to print an impres-` sion on the tube 40, onthemandrel 4:1, which is adapted to be rotated when in printing positionby the shoe 31 on one end of the cylinder 2 0 which is preferably madeof t5 rubber or other compressible material so as to revent slipping.

here are three mandrels Ztl, and each is a hollow tube with closedoutery end'mounted lon a non-rotating post 4:2., and furnished 7u withball bearin s 43 at its base and 44 at its outer end. he posts t2 are inturn eccentrically mounted on a disk Ylon the rotary head 4&6, and areadapted to be moved intermittently through yan arc of 12,0 dei5 grecswith the said head. The eccentric mounting of the posts. providesafli'mited adjustment of the mandrels totake up 'weer l and for otherpurposes.

rllhe ste by step rotation. ofthef head is eo brou ht a out by means ofthe whic have a reciprocating motion and engage the ratchets 51 of thedisk 511 secured, to and rotating freely with the "head 416.' C Motionis imparted to them through the et pinion 52 keyed to the'same shaft,53, there-` withf'the horizontal rack 54oi'i'theupper edge of the slidinbar. 55, which'engages the said pinion, an :the corresponding rack 56in.' the'lower edge thereofat'the oppone@ site end and the segment '5,7which 1s given oscillating movement by the heart cam 5 8 rotated byv theshaft 23, upon which it `is keyed. rll`he cam 58 receives itsv rotaryinotion Afrom the drive shaft 2 2- through thev et idler 29- whichmeshes with the gear 32 and the gear 33 keyed to the cam shaft', andlthe@L roller 59 mounted on, a stud,` on the segment 57 engages the,cam. The cylinder gear 3 1 also meshes with the gear 3 3v and in thismanner receives its motion from the. drive shaft. rlhe sliding bar ismounted in the guides 60 and 61.

ln order to adjust the mandrels er spindles 41 so as to secure a perfect'alinement with the Plate @et the See-te@ @eeen le:

itt f -the said plateand also oscillated so as to pression o n thetubethe head 46 is mountedso that it can be moved bodily to. and from vbringabout perfect parallelism between the face of said .plate andthe'exterior surfaces of the tubes. This is provided for in thefollowing manner: .The head plate 46 is mounted in one end. of a casing47 of the head,and in the other end of this casing is mounted a plate 48through which the in- 1 ner offset ends 44a of the posts 42 extend,

y be secured in any desired. position.

ybeing securedby means of suitable nuts-`49.

. '.Ihis casing is mounted on a round swivel tending into a threadedaperture of the frame is mounted. This screw 38 .is used to move thecasing bodily, and the man-` drels, to and from the cylinder 20. Otheradjusting screws 39l and 39a extend through the base 37 at right vanglesto the screw 38 and bear against a'. depending portion of the headcasing to give the casing and the mandrels the oscillating movement onthe said base. The entire base of the' casing 37 and the parts supportedthereon slide on the dovetail track 34a on the frame in a correspondingslide way 37a in the bottom of said base, and maybe secured at any pointby the clamp 36.

i In order to hold the 'tubesin the printing position while theactuating Vpawls 51 are eing retracted, and maintain them, the

` shaft 53, on which the disk 51a bearing the Afio ratchets 51 ismounted, has keyed thereto a cam 15 against which is pressed a roller 6on a'rockingarm 1,6 by means-of aspring- 7, and a bolt 17 is pressed b aspring 8 into notches' 18a of another dis` 18 keyed'to the said shaft,when the said arm 16 reaches the bottom of the inclined side ofzthe cam,

' -if' the said bolt and one of the notches are in, alinement. The camis so located that it will cause the rocking armll to retract the bolt,through contact of an extension 9 with'a roller 19 on thebolt, at theend of the backward movement of the spring pawls 50 and permit the sameto engage the said notches at the end ofthe forward moveC ment andremain in suchjengagement until the end of the next backward movement.

'As' the outerend of the rocking arm 16 moves inward lat the beginningof the foi'-vv ward motion, the bolt 1 m ust .ride on the outer edge ofthe disk 18 until another notch 18 is brought into alinement there---with, which occurs at the moment the tube reaches printing position.'The spring k8 les -which constantly presses the bolt 17 forward is heldin a tubularrecess in the shank cylinder,

of the holt, between the inner end of the said recess and the plate 10.In this manner each tube is held in position while the platel is passingover its surface and then moved to a lower position while another ismoved into its place, and each mandrel is held stationary' while itstube is being printed, removed and replaced.

i The operation of the machine will be fully understood by those skilledin the art from the foregoing description.

Various modifications ofthe structural details of the machine may bemade, and some of the parts may be changed, omitted or replaced by otherparts without departing from the scope of the invention.
